Description

そして、諸元データ生成部は、車両関連情報受信部が車両関連情報を受信すると、当該車両関連情報が正規の組合せか否かに関らず、対象装置に書込む更新データと共に車両へ送信する諸元データを、車両情報記憶部及び装置関連情報記憶部に記憶された情報に基づいて、対象装置の装置種別、対象装置の属性、対象装置の更新データ関連情報、対象装置のデータ更新に関する書換え環境を示す情報を含むように生成する。更に、パッケージ生成部は、更新データ記憶部より取得した更新データと、諸元データとを含む配信パッケージを生成する。これにより、車両側の装置は、更新データと共に送信される諸元データを受信することで、その諸元データに基づいて対象装置を適切に選択して更新データを書き込むことが可能になる。 Then, when the vehicle-related information receiving unit receives the vehicle-related information, the specification data generation unit transmits the vehicle-related information to the vehicle together with the update data to be written in the target device regardless of whether or not the vehicle-related information is a valid combination. The specification data is rewritten based on the information stored in the vehicle information storage unit and the device related information storage unit, the device type of the target device, the attribute of the target device, the update data related information of the target device, and the data update of the target device. Generate to include information that describes the environment. Furthermore, the package generation unit generates a distribution package including the update data acquired from the update data storage unit and the specification data. Accordingly, by receiving the specification data transmitted together with the update data, the device on the vehicle side can appropriately select the target device based on the specification data and write the update data.

一方、ステップＤ２において「構成情報ダイジェスト」の照合結果が不一致であれば（ＮＯ）、センター装置３は、車両側システム４に「構成情報オール」の送信を要求する（Ｄ３）。この送信が「全データ送信要求の通知」に対応する。それに応じて、車両側システム４が「構成情報オール」を送信すると、センター装置３はそれを受信する（Ｄ４）。そして、センター装置３の個車情報管理部３Ｃは、個車情報ＤＢ２１３に登録されている当該車両の情報を更新する（Ｄ５）。それから、ステップＤ６に移行する。個車情報ＤＢ２１３は、車両側構成情報記憶部の一例である。また、個車情報登録部２０９は、情報更新部の一例である。
尚、ＣＧＷ１３による「同期開始要求」の送信は、ＩＧスイッチ３７がオフされたタイミング等に行っても良い。 On the other hand, if the collation result of the "configuration information digest" does not match in step D2 (NO), the center device 3 requests the vehicle side system 4 to transmit "configuration information all" (D3). This transmission corresponds to "notification of all data transmission request". In response, when the vehicle-side system 4 transmits "configuration information all", the center device 3 receives it (D4). Then, the individual vehicle information management unit 3C of the center device 3 updates the information of the vehicle registered in the individual vehicle information DB 213 ( D5). Then, go to step D6. The individual vehicle information DB 213 is an example of a vehicle-side configuration information storage unit. Also, the individual vehicle information registration unit 209 is an example of an information update unit.
The transmission of the "synchronization start request" by the CGW 13 may be performed at the timing when the IG switch 37 is turned off.

次に、第３実施形態の作用について説明する。図２７に示すように、センター装置３の個車情報管理部３Ｃは、ステップＤ４，Ｄ５を実行すると、個車情報ＤＢ２１３のＥＣＵ情報に「特別フラグ」への書き込みがあるか否かを判断する（Ｄ２６）。図２７における「ＶＩＮ＝０００３」のように、「特別フラグ」に「ＥＣＵ交換」のような情報の書き込みがあれば（ＹＥＳ）、ステップＤ２７に移行してステップＤ７と同様の判断を行う。「特別フラグ」に情報の書き込みが無ければ（ＮＯ）ステップＤ６に移行する。ステップＤ６～Ｄ１２は、第１実施形態と同様に実行される。 Next, operation of the third embodiment will be described. As shown in FIG. 27, when executing steps D4 and D5, the individual vehicle information management section 3C of the center device 3 determines whether or not the ECU information in the individual vehicle information DB 213 has a "special flag" written. ( D26 ). If information such as "ECU replacement" is written in the "special flag" (YES), as in " VIN =0003" in FIG. If no information is written in the "special flag" (NO), the process proceeds to step D6. Steps D6 to D12 are performed in the same manner as in the first embodiment.

ステップＤ２７で「ＹＥＳ」と判断すると、この時点で差分データを生成し（Ｄ２８）、諸元データを生成し（Ｄ２９）、更に配信パッケージを生成して（Ｄ３０）パッケージファイルを送信する（Ｄ３１）。 If "YES" is determined in step D27 , difference data is generated at this point ( D28), specification data is generated ( D29 ), a distribution package is generated ( D30 ), and the package file is transmitted. (D 31 ).
